Egyptian heavyweight Mohamed Elsayed was disqualified from his Olympic boxing semi-final on Friday because he failed the medical examination, organisers said.

Elsayed did not pass the test because of an arm injury sustained in his quarter-final win over Australia's Adam Forsyth. He leaves the tournament with a bronze medal.

The Egyptian's scheduled semi-final opponent, Viktar Zuyev of Belarus, goes through to Saturday's final on a walkover and will win at least a silver medal.

He will meet Cuba's Odlanier Solis or Syrian Naser Al Shami in the gold medal contest.
